    1.1. Air-mechanical foam is the most effective fire extinguishing agent for extinguishing fires of classes A (combustion of solid substances) and B (combustion of liquid substances).

    1.2. To obtain air-mechanical foam, foam concentrates and fire fighting equipment are used. Depending on the area of ​​application, foam concentrates are divided into two classification groups: general and intended purpose. To foam concentrates general purpose include: PO-3NP, PO-3AI TEAS. Foaming agents for special purposes include: “Sampo”, “Morskoy”, “Potok”, “Film-forming”, “Foretol”, “Universal”, POF-9M.


    Special purpose foam concentrates differ from general purpose foam concentrates in their higher fire extinguishing ability due to the use of recycled additives.

    All foaming agents for general and special purposes do not lose their original physical and chemical properties when subjected to repeated freezing and subsequent gradual thawing.

    Energy plants mainly use general purpose foaming agents.

    1.3. To extinguish fires at transformers and reactors, low-expansion air-mechanical foam is used, and at fuel oil and oil industries, medium-expansion foam is used.

    Low expansion foam is obtained using OPDR foam sprinklers and its modifications.

    EXTRACT FROM THE WORK “ORDER OF APPLICATION, TRANSPORTATION, STORAGE AND QUALITY CHECKS OF FOAMING AGENTS FOR FIRE FIGHTING. (INSTRUCTIONS)"

    TESTING METHODS FOR FOAMING AGENTS

    1 . DETERMINING APPEARANCE

    1.1. Appearance The foaming agent is determined visually in a test tube made of colorless glass P2 with a diameter of 30 mm and a capacity of 250 cm 3 (GOST 253336-82) in transmitted scattered light.

    1.2. To determine the crystalline precipitate, a foaming agent pre-filtered at 20 ° C is poured in an amount of 250 cm 3 into a cylinder with a capacity of 250 - 500 cm 3 and placed in a refrigerator at a temperature of (3 + 2) ° C. After 24 hours of exposure there should be no formation of crystalline sediment visible to the naked eye.

    2 . DETERMINATION OF PORNING TEMPERATURE

    2.1 . Equipment

    Test tube P2T-250 TS according to GOST 25336-82;

    test tube P1-16-150 HS according to GOST 25336-82;

    mercury thermometer type TN-6 according to GOST 400-80;

    vessel with a cooling mixture.

    2.2 . Carrying out tests

    A clean, dry glass tube with a diameter of 16 mm is filled with foaming agent to a height of 30 mm. The test tube is closed with a stopper with a thermometer inserted into it and placed in a test tube with a diameter of 30 mm so that the walls of the test tube are at the same distance from the walls of the coupling.

    The assembled device is placed in a vessel with a cooling mixture, the temperature of which should be 5 °C below the expected freezing temperature of the foam concentrate.

    The pour point is taken to be the value established after the decline and rise.

    2.3 . Processing the results

    Determination of the pour point is carried out 3 - 4 times. The final result is the arithmetic mean of all determinations.

    3 . DETERMINATION OF FOAM EXPANSION AND STABILITY IN LABORATORY CONDITIONS

    3.1 . Equipment, reagents

    Device “Tissue Shredder” (RT-1) according to TU 64-1-1505-79. A graduation must be applied to the instrument glass with a division value of 50 cm 3 to the final value of 1000 cm 3.

    Cylinder 2-100 according to GOST 1770-74.

    Stopwatch according to GOST 5072-79, accuracy class 3.

    Distilled water according to GOST 6709-72.

    3.2 . Carrying out tests

    The foaming agent in the amount necessary to obtain a concentration solution is poured into the cylinder and adjusted with distilled water to 100 cm 3 . The resulting foaming agent solution at a temperature of (18 + 1) °C is poured into the glass of the device, the speed switch is set to 4000 rpm, then the electric motor and stopwatch are turned on simultaneously. The solution is stirred for 30 s, the electric motor is turned off and the volume of the resulting foam in the glass is recorded.

    The foam multiplicity is calculated as the ratio of the resulting volume (in cm 3) of foam to 100 cm 3 of the solution taken for testing. The stability of the foam is determined by the time it takes for 50% (50 cm 3) of the foaming agent solution to be released from it.

    The arithmetic mean of three determinations of the foam ratio is taken as the test result.

    3.3 . Determination of foam stability on the surface of ethyl alcohol

    3.3.1 . Instruments and reagents used

    General purpose laboratory scales, maximum weighing limit 200 g.

    Glass glass according to GOST 25336-82, type VN-400, capacity 400 ml.

    Measuring cylinder according to GOST 17770-74, accuracy class 2, capacity 100 ml.

    Glass rod, diameter 4 - 8 mm, length 150 - 250 mm.

    Mechanical stopwatch according to GOST 5072-79, class 2, measurement limit 60 min.

    Rectified ethyl alcohol according to GOST 5962-67 or technical alcohol according to GOST 18300-87.

    3.3.2 . Carrying out tests

    Measure 100 ml of ethyl alcohol with a cylinder and place it in a glass, which is placed on a scale. Foam (obtained in accordance with the requirements of clause 6.2) is applied to the surface of the alcohol in an amount of (8 + 0.5) g. In the event of the formation or destruction of foam in the process of open areas of the surface of the alcohol or peeling of the foam when large air bubbles form, it should be leveled with a glass rod foam over the entire surface of the alcohol, without touching the separating gel-like film.

    A stopwatch records the time from the moment the first portion of foam is applied to the alcohol until open areas of the surface of the alcohol or separating film appear. This time determines the stability of the foam on the surface of the alcohol. The test is carried out three times. The arithmetic mean is taken as the final result.

    4 . DETERMINATION OF FOAM EXPANSION ON A MEDIUM EXPANSION FOAM GENERATOR

    4.1 . Equipment, materials, reagents

    Generator GPS-200 or GPS-600 according to GOST 12962-80.

    A pump providing a solution supply of at least 2 dm 3 /s for (GPS-200) or at least 6 dm 3 /s for (GPS-600) at a pressure in front of the foam generator of 0.6 - 1.0 MPa.

    Drinking water according to GOST 2874-82.

    4.2 . Carrying out the test

    200 dm 3 of a working solution of a foaming agent is prepared in a container. The prepared solution is fed through a suction hose by a pump under a pressure of 0.6 MPa into a pressure hose, at the outlet of which a generator is installed.

    After obtaining stable foam from the generator, fill the container for collecting foam, and the entire volume must be uniformly filled; The formation of voids is not allowed. The mass of foam in the container is determined by weighing on a scale.

    4.3 . Processing the results

    The foam ratio K is determined by the formula:

    where V is the volume of foam, m 3;

    V 1 is the volume of the foaming agent solution in cubic decimeters, numerically equal to the mass of the foam, kg.

    The arithmetic mean of three determinations is taken as the result of the determination.
